7 Application filed July Specification of Letters Patent.

17. 1912. Serial No. 709,911'.

To all 7.01207, I l may concern Be it known that .IJVILLtAM E. SHEEHAN, a citizen of the United States of l-hnerica, residing at No. 301 Madison avenue, in the citv of Johnny, in the county of Albany and State ot'New York, have invented certain new and useful liiiprm'enients in Paper- Making l\lachines, of which the following is a specification.

My invention relates to paper making machines, and the object of my invention is to provide a means for; drying a web of paper. pulp or similar substance; together with such elements and combinations as are hereinafter more particularly set forth and claimed. I accomplish these objects by means of the mechanism illustrated in the ac- ('()ll|t )t\1l- \'l1l}1 drawing in which:

Figure 1 is a side elevation.ofaFourtli-inier paper making, machines provided with my invention, with parts broken away. Fi a 2 is a longitudinal section of the suction ro l. Fig. 3 is a crossscction of the suction roll. Fig. l is an end \lQW of the suction nozzle. showing the roll in section. Fig. 5 is an end view showing a modified form of the suc tion roll. Fig. .(3 is a detail view o'fothc suction roll, showing the porous plug, 1, "l intowhich it tits in the roll, R.

Similar letters refer to similar 'parts throughout the several views.

lIhaYc shown in the drawings my invention applied to a Ffillltll'lliltl' machine, although I do not limit mysclthto that particular. kind of apparatus. l

The couch rolls, A and ll. are mount ed in the usual manner and the paper pulp is deposited on the carrier. 0, after which it is delivered to the felt; l). in the usual maner press roll, 1C. and suction roll. R. I do not, however, limit myself to the position of the suction roll, 11, nor to its arrangement as shown in Fig. l beneath the press roll, E, but. l contemplate using the suction roll, it, without any other roll engaging it or the felt or carrier passing over it. My illustration of the suction roll, R,; in operative connection with the press roll, E. is piu'elyurbitrary and is not to be considered as even advisable in operation.

My suction roll, R, is hollow and is made of metal or any other hard material, or it a porous substance; but, in any event, it is. provided with a series iasses over of openinos or holes, T, through the shell,

0. extent ing through the periphery. the end of the roll near the peri leery and preferably in each end thereof, fplace an opening extendinginto the interior of the roll which may he closed with the screw bolts,'I", F, for the purpose of emptying the roll. {supply water or other liquid three 11 a pipe thpassiug'preferably through tit iiiiT ri es.

thimhle, l'lpwhich extends throutjy h the hub,

end of the roll. h overflow pipe,.K, through the thimble, H, which has its discharge port, 7', a short distance from the interior surface of the shell of the roll. Through the thimble, H, I also pass a suction-pipe, nozzle, M, open at the end, but provided with a flange, N, which when in operative position tllJPl'OittllltS near but does not c0ntact with theinncr surface of the shell, 0, of the roll. The nozzle, M, is sulliciently long to embrace the line of the holes, '1. extending from oneend of the roll to the other and of sutiicient width to e1nbrace several of such lincsof holes, three, as shown in Fig. 3, but I do not limit myself to the length or width of the nozzle which' be constructed to embrace more or lossmay of the holes as may be desired. Into each of the holes. 'l, I place a porous plug, P, wluch may he made of felt or other material.

The suction pipe. it, is connected with a suction pump, not shown.

The operation of my invention is astollows: The roll, R, is mounted in a paper making machine and the web of paper or pul is conducted to it in any suitable manner. 'l he roll supplied with water overflow, ,l'. The water seals alarge number, almost. alhof the porous plugs, P, as shown in Fig. 23; suction is which draws the air the porous plugs embraced b M. and also takes out of the rol the air above the water in the roll, the air taking the di rcction hown by the arrows in Fig. 3, and

the water and air passing through ,the pos rous plugs, P, taking the directionshown by the arrows in Figs. 2 and 3, andthereby web of paper and pulp as it the roll. As the roll revolves the porous plugs come over the nozzle, M, and are operated on by the suction produced through the nozzle.

Because of the fact that the flange, N,of the. nozzle is free and clear of the interior.

drying the L, whichhas a flaring re ferably I mot lace an up to the point of a applied to the pipe, L, l and the water through the nozzle,

no i

'amefi'ective amount of suctionmay direct'edto the paper or pulp in a positive and practical manner.

. My IIIVeIIlZIOIIIS simple inits construction and 1OPB1'2IUOD, inexpensive 1n its maintenance, readily adjusted and "performs the work required of it in an economical and satisfactory manner.

I show, in Fig; 5 a modified form of'my invention in which the suction pipe, L,'is unprovided with a nozzle and there is no water placedin the roll.

' to secure by Letters Patent is:

1." In a paper making machm e, ahollow suction roll provided with a series of open ings'therethrough; a series of porous plugs What I claim as my invention and desire placed in said openings; means for supply mg hquid to sand rol ;v an overflow in said r01 placed a short distance from the shell; an exhaust pipe entering said roll; a nozzle on said exhaust pipe provided with a flange mounted to just clear the shell and to em-' brace a number of said stantially as described. j

porous plugs, sub- 2. In a paper'making machine; a hollow suction roll provided wltha series of openi mgs therethrough; aser1es of porous plugs placed 1n said openlngs; an exhaust pipe entering said roll, whereby s'uction may be applied to the wet paper and pulp passing over the roll, substantially as described.

In testimony whereof I have aflixed my signature in presence of two witnesses. WILLIAM SHE EHAN. v I Witnesses:
